The effect of the wood flour content and its chemical fiber treatment (amino-silane) on the mechanical properties of the WPC was studied by ultrasonic methods and mechanical tensile test. The elastic properties of the studied PP/OWF compositions are discussed and both of the mentioned evaluations give similar tendencies even if the characterization methods are somewhat different. As a result, the increase of the fiber content and the addition of the amino-silane coupling agent is shown to improve the rigidity of composite materials. Eventually, a correlation factor between the estimated Young's moduli is established between the ultrasound values (for ε < 0.05%) and mechanical values (for 0.05 < ε < 0.25%). Ultrasound measurements are discussed as an alternative method for the elastic properties evaluation. %G English %2 https://imt-mines-ales.hal.science/hal-02765687/document %2 https://imt-mines-ales.hal.science/hal-02765687/file/2020%20-%20Bouhamed%20-%20Post%20print%20-%20Ultrasound%20evaluation%20of%20the%20mechanical%20properties%20WPC%20including%20olive%20wood%20flour.pdf %L hal-02765687 %U https://imt-mines-ales.hal.science/hal-02765687 %~ INSTITUT-TELECOM %~ CNRS %~ EM-ALES %~ LMGC %~ COMUE-NORMANDIE %~ MIPS %~ UNIV-MONTPELLIER %~ UNILEHAVRE %~ LOMC %~ INSTITUTS-TELECOM %~ UM-2015-2021
